Title: Operation controller for reverse-osmosis membrane condenser
Inventor: TAKADA KAZUHARU
IPC: B01D61/06
Filed: 1987-07-02
Abstract: PURPOSE:To increase a liquid permeation rate without causing damage to a reverse-osmosis membrane, by providing a high-pressure pump with a speed-changing means, controlling the high-pressure pump after a measured liquid permeation rate is compared with a predetermined desirable rate, and decreasing the operation speed of the high pressure pump if a supplying pressure exceeds a tolerance-limit pressure for the reverse-osmosis membrane. CONSTITUTION:The liquid permeation rate Q measured by a liquid flow sensor 14 placed in a pipe 9 for transmission of a penetrated liquid from a reverse-permeable membrane tank 1 is compared with a predetermined liquid rate Qo of liquid permeation. In the case of Q<Qo, a controller 15 signals a speed-changing means 11 of a high-pressure pump 6 to increase its revolution number or reciprocation number; and in the case of Q>Qo, it signals to reduce the number. At the same time, the supplying pressure P and temperature T of a liquid to be condensed are measured by a pressure sensor 13 and a temperature sensor 12 placed in a supplying pipe 8 for supplying the liquid to be condensed. The controller 15 compares the measured value of the supplying pressure P with a tolerance-limit pressure Pa which is lower by a suitable value than the critical pressure Pm at which a reverse-permeable membrane 2 suffers damage at the temperature T of the liquid to be condensed. Where P exceeds Pa, the controller 15 signals the speed-changing means 11 to reduce the revolution number or reciprocation number.

Title: Method for controlling intermittent air lift device and system therefor
Inventor: MAKINO MICHIO
IPC: C02F1/00
Filed: 1991-06-11
Abstract: PURPOSE:To automatically keep water quantity in the vicinity of set value by comparing the measured water quality value with the preset water quality value and controlling charge of a water-quality improver by difference thereof. CONSTITUTION:When pH of a lake is 4.5, high-concentration line water (pH 9) is continuously injected into the respective pumping devices 2a, 2b, 2c and pH is regulated to 6. In the case of regulating the set value of pH to 6, when the value of a pH sensor reaches 6, output of comparison value 5 is inputted to a controller 9. When a pump 8 of chemicals is stopped, a pumping device 2 performs only circulation of water and pH regulation is stopped. Thereby supply of chemicals to the pumping device 2 unnecessary for pH regulation is automatically stopped. Further, when pH value is lowered, supply of chemicals is restarted. Accordingly, water quality is automatically controlled by comparing the measured value based on the various sensors with the preset value.

Abstract: PURPOSE:To restrict the loss of light to a minimum by forming an infinite-point correction optical system capable of arbitrary setting of optical length without changing optical magnification, and setting the magnification so as to obtain the optimum incidence condition. CONSTITUTION:The light of a mercury lamp 13 is converged at a point A by a condenser mirror 14. At a point separated by a distance f1 from the point A, the light is collimated by a collimator lens 19, and divided by a half mirror 20 in accordance with the number of alignment systems. An imagery lens 23 is arranged at a position where the conjugate image of the point A is focused at a position A' corresponding to the light source of an alignment optical system. Practically, the focal length of f2 of the lens 23 and the distance between the lens 23 and the point A' are made equal. The incident angle theta2 to the alignment optical system is given by a formula theta2=f1/f2.theta1 (light source side incident angle). The values of f1 and f2 are so set that theta2 becomes optimum with respect to the illumination N.A. of the alignment optical system, and the optical length of the collimation part is changed. Thereby the direct light transmission to an arbitray alignment system is enabled.
